He shall receive a blessing from the Lord, and mercy from God his Saviour.

He beareth away a blessing from Jehovah, Righteousness from the God of his salvation.

He shall receive blessing. The more effectually to move the minds of the Israelites, David declares that nothing is more desirable than to be numbered among the flock of God, and to be members of the church. We must here consider that there is an implied contrast between true Israelites and those of them who were degenerate and bastards. The more license the wicked give themselves, the more presumptuous are they in pretending to the name of God, as if he were under obligation to them, because they are adorned with the same outward symbols or badges as true believers. Accordingly, the demonstrative pronoun this, in the following verse, is of great weight, for it expressly excludes all that bastard generation which gloried only in the mask of external ceremonies. And in this verse, when he speaks of blessing, he intimates that it is not those who boast of being the servants of God, while they have only the name, who shall be partakers of the promised blessing, but those only who answer to their calling with their whole heart, and without hypocrisy. It is, as we have already observed, a very powerful inducement to godliness and an upright life, when the faithful are assured that they do not lose their labor in following righteousness, since God has in reserve for them a blessing which cannot fail them. The word righteousness may be explained two ways. It either means all the benefits of God, by which he proves himself to be righteous and faithful towards his people in keeping his promises to them, or it denotes the fruit or reward of the believer's righteousness. Indeed, David's meaning is abundantly manifest. He intends to show on the one hand, that it is not to be expected that the fruit or reward of righteousness will be bestowed on those who unrighteously profane God's sacred worship; and on the other hand, that it is impossible for God to disappoint his true worshippers; for it is his peculiar office to give evidence of his righteousness by doing them good.

He shall receive the blessing from the Lord - literally, "He shall bear away a blessing from Yahweh." The blessing here referred to means His favor and friendship. He shall be recognized and treated as His. In other words, God bestows His favor on those who possess the character here referred to.
And righteousness from the God of his salvation - He shall be regarded and treated as righteous. Or, he shall obtain the divine approval as a righteous person. The idea of the psalmist would seem to be, not that he would obtain this as if it were a gift, but that he would obtain the divine "approval" of his character as righteous; he would be recognized and dealt with as a righteous man. He would come to God with "clean hands and a pure heart" Psalm 24:4, and would be welcomed and treated as a friend of God. The wicked and the impure could not hope to obtain this; but he who was thus righteous would be treated according to his real character, and would meet with the assurances of the divine favor. It is as true now as it was in the days of the psalmist, that it is only the man who is in fact upright and holy that can obtain the evidences of the divine approval. God will not regard one who is living in wickedness as a righteous man, nor will he admit such a man to His favor here, or to His dwelling-place hereafter.

He shall receive the blessing - Perhaps alluding to Obed-edom, at whose house the ark had been lodged, and on whom God had poured out especial blessings.
And righteousness - Mercy: every kind of necessary good. It is the mercy of God that crowns the obedience and fidelity of good men. For what made them good and faithful? God's mercy. What crowns their fidelity? God's mercy.

He shall receive the blessing from the Lord,.... Or "who receives" (l); the future for the present; and so is a continuation of the description of a person proper to enter and abide in the church of God, as Psalm 24:6 seems to require; even one who has received every spiritual blessing in Christ in general, special grace out of his fulness; particularly the blessing of pardon, as also adoption, and a right to eternal life; though it may be that the following clause is explanative of this;
and righteousness from the God of his salvation; from Christ, who is God his Saviour, the author of salvation; and who has brought in an everlasting righteousness, which is in him, and is a gift of his grace, and is received from him by faith, and is a great blessing indeed; it secures from condemnation and death, and entitles to eternal life.

righteousness--the rewards which God bestows on His people, or the grace to secure those rewards as well as the result.

The blessing - Grace and glory, and all other good things.
